Tim Berners-Lee offered his "Five-Star" plan for open data. He said public information should be awarded a star rating based on the following criteria: one star for making the information public; a second is awarded if the information is machine-readable; a third star if the data is offered in a non-proprietary format; a fourth is given if it is in Linked Data format; a fifth if it has actually been linked.
